The Dallas Stars have been trying to sign three of their players to extensions, but if deals can't be ironed out by Wednesday morning, there's a good chance they'll be traded.

Forwards Jaromir Jagr, Derek Roy and Eric Nystrom are all set to become unrestricted free agents July 5.

Stars GM Joe Nieuwendyk has been in talks with each of their agents, but so far he's come up empty.

"I don't really have any update on that," he told the Dallas Morning News.

In fact, it's believed negotiations with Roy's camp have ceased and a trade now appears the likely outcome.

Several teams are interested in Roy, including the Anaheim Ducks, Ottawa Senators, Toronto Maple Leafs and Vancouver Canucks.

Jagr, who has attracted the interest of the Philadelphia Flyers and Boston Bruins, among others, could also be on the move. He's currently discussing a one-year extension with the Stars, but the two sides haven't been able to finalize a dollar amount.

Nieuwendyk admitted he's been "listening to calls" on all three players, and trade talks could start heating up Tuesday.

Veteran defenseman Stephane Robidas is also being talked about, though it's unclear if the Stars would move him.

Robidas, who owns a no-trade clause and can have final say on any deal the team tries to make, has one-year left on his contract beyond this season at a salary cap hit of $3.3 million, though he'll earn $2.85 million next season.
